Asymptomatic infection with either Entameba histolytica or Giardia lamblia was found in 61 per cent of the residents of a dormitory in an institution for the mentally retarded; two other dormitories had rates of 20 per cent and 22 per cent. Drug therapy was successfully undertaken in all three dormitories, and environmental improvements were introduced in the heavily infected dormitory. A one-year follow-up showed a reduction in parasitic disease in two dormitories but, in the most heavily infected dormitory, infection had returned to pretreatment levels.
在一所智障人士机构的宿舍中,61%的居民被发现无症状感染溶组织内阿米巴或蓝氏贾第鞭毛虫;另外两个宿舍的感染率分别为20%和22%。三个宿舍均成功进行了药物治疗,并对感染严重的宿舍进行了环境改善。一年的随访显示,两个宿舍的寄生虫病有所减少,但在感染最严重的宿舍,感染率已恢复到治疗前水平。
